  Hi,

    You may simply check TYS to find out how many questions appear through the years.

    School papers, I believe, follow closely to the style of Cambridge papers.

    Thanks.

  Cheers,

  Hi,

    Probability questions typically cover the following concepts and skills:

    1. drawing a possibility diagram to show various outcomes

    2. drawing a tree diagram to show various outcomes

    3. addition and multiplication principles

    4. probability related to other topics like cumulative frequency and dot diagram

    Once you know what matters, it should not be difficult to pin down these with constant practice. Thanks.

  Cheers,
  Wen Shih

  Yes, for practice, you can buy roulette wheels, chips, cards, etc, from a hobby shop at Plaza Singapura.

  Also, the cigarette smoke in MBS' smoking level travels up to the non-smoking level, all MBS croupiers and regulars are also gambling with lung cancer.

  In RWS, the smoking section is isolated in a hall away from the main hall, which is smoke-free.

  If you read today's papers, MBS' has a higher-than-expected (calculated based on total amount wagered) profit margin this quarter, which means should they continue at this rate, you've a higher probability of winning (possible fallacy) at RWS compared to MBS.

  This problem asked us to find some probabilities involving a spinner. Let's look at some definitions and examples from the problem above.

  In order to measure probabilities, mathematicians have devised the following formula for finding the probability of an event.

  
  

  Probability Of An Event

  P(A) =  The Number Of Ways Event A Can Occur The total number Of Possible Outcomes
